Parts for your 1999 Ford Falcon-Brake wheel cylinders

1999 Ford Falcon brake wheel cylinders

Technical references show brake wheel cylinders are indeed relevant to many 1999 Ford Falcon (AU Series) variants. The Ford AU Falcon Workshop Manual (1998–2002) and Gregory’s Service and Repair Manual note rear drum brakes on mainstream trims (e.g., Forte/Futura), which use hydraulic wheel cylinders. Ford’s Microcat electronic parts catalogue and PBR/Bendix Australia parts listings also catalogue rear wheel cylinders for AU I–III Falcons with drums. By contrast, models equipped with four-wheel discs (common on XR and some Fairmont/Ghia packages) do not use wheel cylinders. So, for a 1999 Falcon with rear drums, wheel cylinders are fitted, for disc-rear cars, they’re not applicable.

On drum-brake AU Falcons, the brake wheel cylinder is the small hydraulic actuator that pushes the brake shoes outwards against the drum. When the driver taps the pedal, fluid pressure travels down the line and the cylinder’s pistons shove the shoes into the rotating drum, slowing the car. Simple, robust, and effective — provided they’re clean, dry and free-moving.

As part of routine servicing, it’s smart to check for weeping under the rubber dust boots, damp patches inside the drum, uneven shoe wear, or a spongy pedal. Any sign of fluid around the backing plate or a pull under braking points to a cylinder issue. Because they work as a pair, replacements are best done on both sides of the axle to keep braking even. Typical AU drum setups run a 7/8 in (about 22.2 mm) bore cylinder, but always match the bore to what’s already fitted.

When replacing, use a proper flare-nut spanner on the line, fit new copper washers/seals where applicable, and inspect shoes, springs and drums at the same time. If the shoes are soaked or near their wear limit, replace them together with the cylinders. After refitting, bleed the system thoroughly — DOT 4 fluid is commonly specified on AU Falcons, check the reservoir cap — and adjust the shoes so they just brush the drum before final bedding-in. A road test should deliver a firm, even pedal and straight-line stops.

Preventative care helps: flush brake fluid every two years or 40,000 km, keep the adjusters free, and look for early tell-tales like a damp dust boot or dark staining inside the drum. Quality cylinders from reputable Australian suppliers will go the distance if the fluid stays fresh and the shoes are adjusted correctly.

Does every 1999 Falcon have brake wheel cylinders?

No. AU Falcons with rear drum brakes do, variants with four-wheel disc brakes do not. If you’re unsure, look through the rear wheel: a solid drum indicates wheel cylinders, a visible calliper and ventilated/solid rotor indicates discs without wheel cylinders.

What are the signs the wheel cylinders need attention?

Common giveaways are a soft or sinking pedal, the car pulling to one side under brakes, fluid weeping under the cylinder dust boots, or brake shoes contaminated with fluid. Any of these means inspection is due, and if there’s leakage or sticking pistons, replacement is the go.

How often should they be serviced or replaced?

There’s no fixed kilometre count for replacement — it depends on condition. During regular services, check for leaks and free movement. Refresh brake fluid every two years/40,000 km, and inspect the cylinders whenever the rear drums are off. Replace in axle pairs if one fails.
